Document Summary
Species: a population of organisms capable of interbreeding and producing fertile offspring. Each species is genetically distinct from other species. Taxonomy: the science that identifies, names and classifies new species. Carl von linne (linnaeus) developed the basic system of naming and classifying thousands of organisms that biologists have used for centuries. Binomial nomenclature: species are assigned a latinized two-part name. First letter is always capitalized, the second word is never capitalized, and the entire binomial is italicized. Allow people everywhere to discuss organisms without confusion. Genus: a group of species with similar characteristic. Classification: a conceptual filing system that arranges organisms into larger categories. Includes domain, kingdom, phylum, class, order, family, genus, species, and subspecies. The concept of species is based on our observations that earth"s biological diversity is packaged in discrete, recognizable units, and not as a continuum of forms grading into one another.
